不同隔震体系地震反应分析对比

Contrast of Seismic Response of Different Isolation System

本文借助于有限元软件SAP2000对某工程采用的传统结构、纯橡胶支座隔震、纯滑移支座隔震及并联复合隔震四种方案进行时程分析对比。结果表明:三种隔震体系都有明显的隔震性能,且并联复合隔震体系隔震性能介于纯橡胶垫隔震体系和纯摩擦滑移隔震体系之间,合理控制复合隔震的参数可得到一种隔震性能优良的隔震体系。

In this paper,four isolation programs was compared in time-history analysis by finite-element software SAP2000.The results proved that three kinds of isolation systems had obvious isolation effect and the isolation effect of composite isolation was located between rubber isolation system and sliding isolation system.Besides,composite isolation is a isolation system of good performance in reasonable isolation parameters.
